Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable within the operational limits defined in the datasheet. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues. Check for any specific handling instructions related to the no-lead package type during soldering processes.

Oscillators Selection Notes

Select this component when a precise 37.087912 MHz clock source is required for LVCMOS-compatible logic families. Consider the ±50ppm stability specification to ensure it meets the jitter and timing accuracy requirements of the application. The choice is appropriate for designs constrained by the 2.0x1.6mm package size and the need for a standby feature to reduce power consumption during idle periods.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small outline package. These oscillators are designed to replace discrete crystal and buffer combinations, providing a ready-made clock solution for modern electronics manufacturing.

Oscillators Replacement Considerations

Direct substitutes must match the 37.087912 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal characteristics if replacing with components from other manufacturers.
